1.0 - Introduction

TA-25NL / TA-45NL

Temperature Advanced Calibrators TA-25NL and TA-45NL generate temperature in the insert in order to calibrate thermocouples, RTDs, glass thermometers, thermo-switches. Besides providing high accuracy temperature values, it also allows the measurement of signals generated by the thermo-element which is being calibrated. This is possible due to an embedded calibrator specific for these types of signal, including 4-20 mA. Thus, they incorporate the functions of dry block, standard thermometer and calibrator for RTD, TC and mA, stirred liquid and blackbody source.

TA-45NL calibrator model generates temperatures from -45 ºC to 155 ºC

TA-25NL calibrator model generates temperatures from -25 ºC to 155 ºC.

The calibrator also provides an input for an external probe to perform the temperature control from a standard sensor (optional) inserted in the same measuring zone of the sensor to be calibrated, increasing the accuracy and decreasing setpoint errors and loading effects. The standard sensor calibration curve follows the parameterization of Callendar-Van Dusen.

They present a wide variety of programming resources, allowing the performance of automatic calibrations. In this case, the sensor is placed in the insert and its electrical terminals are connected to the embedded calibrator. The operator defines the calibration points and the number of repetitions (task), then the process is started and all the sequence is automatically accomplished. After completing the task, a Calibration Report is issued and it can be printed directly on a USB connected printer or a PDF document can be generated. It has HART® communication (optional) for reading and setting parameters of field devices that have this protocol.

Another way of performing automatic documented calibrations is by means of Calibration Software for PC/WindowsTM, which uses USB communication or Ethernet to connect the computer.

TA Calibrators have also many other features, such as:

RTD input for 2, 3 and 4 wires. Table IEC 60751, JIS or Callendar-Van Dusen user-configurable. Engineering units configurable to °C, °F and K.

Present inputs for mA, thermocouples and thermo-switches. Thermo-element reading scaled to ITS-90 or IPTS-68. Use of internal standard thermometer. Accuracy to 0.1 ºC, stability of 0.02 ºC and resolution of 0.01ºC. Carry out completely automatic calibrations without the use of a computer. Built in Web Server, Ethernet communication and USB serial Communication. USB port for software/firmware upgrade. HART® Communication Protocol (optional) with internal resistance configurable,

transmitter power supply and latest DD as option. The electric signal calibrator is independent from the dry block function. Display indication when the temperature reaches the desired value. 5.7 inches touchscreen display that eases the operation and configuration of the

calibrator. Internal regulated 24 Vdc power supply for 2-wire transmitters. Independent circuit for over-temperature protection and safety. Insert to choose, soft carrying case, handles and test leads included.

Thermal Fluids suitable for use with the insert (AG)

Low viscosity and safe operating temperature are the most important characteristics when choosing a heat transfer fluid to produce high homogeneity in the bath. How less viscous, how better the fluid circulation will be and homogeneous heat produced in the middle. We recommend using the following heat transfer fluids for models TA-25NL and TA-45NL: Viscosity Fluid Flash point* Usable range

Viscosity increases

ethyl alcohol 16 °C -50 °C to 15 °C Mixture of ethylene glycol and water (50% of each)

------------- -30 °C to 90 °C

Water ------------- 5 °C to 90 °C Silicone oil type 200.05 133 °C -40 °C to 130 °C

Silicone oil type 200.10 211 °C -30 °C to 209 °C

*Flash point is the temperature at which a vapor will ignite if exposed to a flame. When the flame is removed, the vapor stops burning.

At temperatures near the lower end of the range, the thermal fluid becomes very

viscous. It can disturb the circulation and increase the cooling time. Above the upper end, there is high evaporation of the fluid compromising the stability of the thermal medium.

If you use the insert with stirred liquid it is necessary to insert the magnetic stirrer (cross shape) at the bottom of the provided insert. The speed of the stirrer is regulated through the STIRRER option in Calibrator mode. Press STIRRER to turn on and off the stirrer, and select the speed between Low, Medium and High options in - and + buttons.

A good fit ensures good uniformity for various types of fluids: alcohol (low temperature), silicone oil (high temperature) etc. Be careful not to accelerate too much the motor so that the magnetic stirrer stops rotating at the bottom of the insert. This will worsen the good homogeneity of the calibrator.

To use the insert with the stirred liquid a good practice is to place first the sheath of the probes or thermometers to be calibrated and then fill up the fluid to a level around 2.5 cm below the top of the insert. This ensures that no overflow occurs either by the introduction of sensors, or by thermal expansion of the fluid. If the level starts to fall during use due to evaporation of the fluid, fill up again adding more fluid. Thus the minimum immersion will not be compromised.

For more accurate measurements use a calibrated probe placed together with the sensors to be calibrated and connected to the external probe input. The calibrator will now control the temperature of the block using this temperature as reference (see item 2.1.2 - External Probe Connection). It is also possible to read the indication of this probe in the RTD Pt-100 auxiliary input.

presys


Page 5

Black Body Insert (BB) Placing the insert BB inside the well of the block of the calibrator provides it with a

good black-body cavity with emissivity above 0.95, suitable for calibration of infrared thermometer.

For more accurate measurements use a calibrated probe placed in the side hole of the bath and connected to the external probe input. The calibrator will then control the block temperature using this temperature as a reference. It is also possible to read the indication of this probe in the Pt-100 RTD auxiliary input.

Align the infrared thermometer to be calibrated with a black body cavity of the calibrator in a vertical position.

The distance of the thermometer to be calibrated in relation to the bottom of the blackbody cavity should comply with specification of its technical manual.

2.1.1 - Probe Settings

There are two different references to control the thermal block: Internal

Reference and External Reference. The Internal Reference is a sensor built into the block. The External Reference is an option for more accurate measurements. The

control reference comes from a Standard Sensor placed inside the insert, among the DUT (devices under test). This Standard Sensor, with Callendar-Van Dusen parameters, eliminates adjustment errors and block loading effects.

It can be used both in control and measurement mode. When used in measurement mode, the probe indication is displayed on the screen and the control is made by the internal probe.

Fig. 08 - Choosing the Type of Temperature Reference

To select the Reference between Internal and External, touch the REFERENCE

bar. When selecting External Reference, the Callendar-Van Dusen parameters must be set. It is also necessary to choose if the External Probe is going to control the block or not.

ID: Set an identification for the sensor R0 (): The last resistance measurement in 0 °C of the sensor A, B, C: Callendar-Van Dusen coefficients Low (°C): Lower value of the reference sensor calibrated range High (°C): Higher value of the reference sensor calibrated range The coefficient values can be found in the Reference Sensor Certificate. pr

2.1.2 - Input Settings

The INPUT menu has the following options:

Fig. 11 - Input Menu Options

For OHM measurement, you should also select between 2, 3 or 4 wires options. For RTD input, it should be chosen the type between Pt-100, Pt-1000, Cu-10 or

Ni-100 (standard table used), the number of lead wires (2, 3 or 4 wires) and the temperature scale (ITS-90 or IPTS-68). There is also the option to configure the Callendar-Van Dusen coefficients of the sensor, selecting the option CVD and the desired curve in the list.

Fig. 12 - Options for RTD Input

To create new CVD coefficients, press (edit), and ADD button. The curves appear in the created list as identified in ID.

For TC (thermocouple), you must select the thermocouple type and the type of cold junction compensation (CJC): Internal or Manual. In Internal option, the

presys


Page 12

compensation is done internally; In Manual you must provide the value of the temperature of the cold junction to the calibrator.

The option SWITCH has two ways to be used. When entering the SWITCH function, the input works as a continuity measurement between RTD2 and RTD4 terminals. When there is continuity, the input shows CLOSED, if not, indicates OPEN. The input also records the temperature value of the block at the time of contact opening / closure.

Using the option THERMOSWITCH TEST, the calibrator performs cycles registering the thermoswitch opening and closure interactively, in order to find the setpoint temperature of the thermoswitch and its respective hysteresis. In Setpoint Hi set a temperature above the opening of the thermoswitch contact. In Setpoint Lo, use a value below the setpoint discounted hysteresis. E.g.: To test a thermostat of 50 °C setpoint and 5 °C hysteresis, Setpoint HI can be set to 55 °C and Setpoint LO to 45 °C.

Fig. 13 - Switch Auto Test Parameters

It is important that the number of cycles be at least 3. By selecting this amount you can check the repeatability of the thermoswitch. For the accuracy, when choosing higher accuracy levels, the temperature ramp times will be higher too. If a Report is needed for this test, use the TASK function.

The NONE option turns off the input function. When the input sensor breaking occur (RTD, resistance or probe) the display will

show the burn-out warning identified by question marks illustrated below:

Fig. 14 - Burn-out Warning

If an out of range signal is injected, a message of UNDER or OVER range appears.

SCALE: For the current input, it is possible to use the scale function:

Fig. 16 - Option for mA Input: SCALE

It establishes a linear relationship between the mA input signal and what is shown

Fig. 17 - SCALE Function (LINEAR)

The scaled indication at the display (#) may represent any engineering unit, such as: °C, % etc.

The number of decimals, up to 4, shown at the display may be configured. The value for Input High must be necessarily higher than Input Low. On the

other hand, Scale High and Scale Low may have any relationship between themselves: higher than, lower than or equal to, and they may have a signal before them. Thus direct or reverse relationships may be established. pr

OK button. To disable, turn the function OFF.

2.1.4 - Saving Current Configuration (Memory Manager)

The TA Series calibrators admit several special functions that may become of frequent use. In these situations, it is useful to store such settings in the instrument in order to save time. After setting the desired calibration mode (input type, probe reference or special

function), press the icon > MENU, and the button MEMORY MANAGER. On the option CREATE NEW can be given a name for this configuration and a description. Press the SAVE button. The operation that was being performed by the TA Calibrator shall be stored in memory identified by the name given to it. To use it again, even after the calibrator is turned off and on, select the name of the desired setting and press the LOAD button. The SAVE AS DEFAULT button sets the current configuration as the default configuration of the calibrator. Thus, every time the calibrator is turned on, this will be the initial configuration of the calibrator.

2.2 - HART® Configuration The TA Series Calibrators can be used to read and set parameters in devices that

have HART® Communication Protocol. The HART® Protocol allows digital communication between master (in this case, the TA Calibrator) and the slave (field instrument) superimposed on the 4-20 mA analog signal. To access this function from the main menu, select the HART® option.

The HART® Communication of TA Calibrators is an optional module. The calibrator has three versions: NH (without HART® Communication), CH (HART® Calibrator) and FH (Full-HART® configurator with DD library).

The CH option has basic and universal commands for HART® communication (zero, span, trim mA etc.) that allow you to adjust the range of the instrument, monitoring the primary variable, current adjustment etc. The FH option, in addition to basic and universal commands, is provided with the DD library (Device Description) from FieldComm Group and allows the setting of specific parameters of each instrument.

The following description is valid for CH and FH options.

2.2.1 - HART® Connections

To the connections shown in Figures 19 and 20, use the mA INPUT + HART®

option and INTERNAL RESISTOR enabled. In this mode, the 250 resistor is activated internally in series with the calibrator mA input. The calibrator can measure current from the transmitter and also read and set parameters via HART®. If the internal resistor is not enabled, an external resistor of at least 150 Ω must be inserted in series with the mA input. To power the transmitter, can be used TPS source (Fig. 19) or an external source (Fig. 20).

2.2.2 - Starting Communication

After defining HART® connection type, inform the ADDRESS of the HART® device

and press the CONNECT button. If the instrument address is unknown, you can use SEARCH button to search the device address in the range from 0 to 15.

Up to 15 devices are allowed on HART® network (address 1-15). In connection with a single field instrument with poll address 0 and mA INPUT + HART® connection, the primary variable can be read either in analog (4-20 mA) and digital form (HART®).

When connected, data appear in the DEVICE INFO tab, identifying the instrument such as TAG, manufacturer, description, message, date, measuring range and input filter (damping). Some of these parameters can be changed in the DEFAULT SETTINGS. 2.2.3 - Adjusting the Measurement Range of a HART® Transmitter

In DEVICE INFO tab, the MIN and MAX fields indicate the measuring range of the

HART® transmitter. For PV (primary variable) equal to the MIN value, the transmitter should generate 4 mA. For PV (primary variable) equal to MAX value, the transmitter should generate 20 mA. The maximum allowable range of the transmitter is shown just above (RANGE ...). To edit the range of the transmitter, just change the MIN and MAX values and press the SAVE RANGE button.

On this screen you can also edit the unit of the primary variable and the input filter (damping). pr

2.2.4 - Adjusting the Measurement Range of a HART® Transmitter with Reference

Another way to adjust the range of the transmitter is generating the minimum and maximum values of the desired range in the transmitter input and adjusting these values as minimum and maximum (set by reference). To adjust the range of a temperature transmitter, insert the transmitter in the thermal block, choose the Reference, and set the temperature. Select Input mA and press the HART® button. The temperature generation will work as the standard value for the adjustment range of the instrument.

Fig 22 - Quick HART® Adjustment with Reference

Generate the temperature to the transmitter input corresponding to the lower range value wait the stabilization and press the button. Transmitter will generate 4 mA to this value. Generate the temperature to the transmitter input corresponding to the upper range value wait the stabilization and press button. Transmitter will generate 20 mA for this value.

Another way to do this adjust is entering in the HART® option through the MAIN MENU, set the connection type, address and then press CONNECT. Select the MONITOR tab. In this screen are shown the value of the primary variable (PV) read by HART® (digital), the current that the transmitter wants to generate (AO - DIGITAL OUTPUT), and the current measured by the TA Calibrator (ANALOGIC READ). Set the block temperature pressing OUTPUT and adjust the transmitter range pressing the ↓ Inf Range and ↑ Sup. Range buttons.

Fig. 23 - Adjusting the Measuring Range of the HART® Transmitter with Reference

2.2.5 - Checking / Adjusting HART® Transmitter mA Output

In DEFAULT SETTINGS, the output current of the HART® transmitter (output

trim) can be adjusted according to current measured by the TA Calibrator. You can make this adjustment only when the TA Calibrator is connected to a single transmitter with address 0, in the mA INPUT + HART® option of connection, since the calibrator needs to measure the current to make the adjustment.

Before performing the adjustment, a transmitter output current check can be performed by pressing the CHECK button. The transmitter will generate fixed current (4, 8, 12, 16, 20 mA) and the calibrator will show the measured values for each point.

To adjust automatically, simply press the AUTO button. The calibrator will send the command to the transmitter to generate 4 and 20 mA (fix), makes the measurement of these points, and adjusts the output (trim). The adjustment is completed when D/A Adjustment Completed message appears.

The LEAD TIME sets each points stabilization time (in seconds). pr

2.3 - Automatic Tasks In TA Calibrators, automatic calibration tasks can be created and performed. This

option can be used to generate calibration work orders for sensors, transmitters and indicators.

2.3.1 - Creating Tasks

To create tasks from the main menu, select CALIBRATOR. Select the desired type of input and probe configuration. For example, to calibrate a temperature transmitter, select the probe configuration (Internal or External Reference) and mA input (which will be connected to the current output of the transmitter). For a temperature indicator, e.g., selected NONE for the input.

Press the icon, and select TASKS and CREATE NEW TASK. Fill at least the serial number of the instrument to calibrate, instrument TAG, lead

time (time, in seconds, for the complete stabilization of the system), maximum error allowed for the instrument to be calibrated (in % of the span, reading or full scale), calibration range (highlighted fields). For the SWITCH tasks, the error fields are filled in the next step.

Go to the As Found/ As Left tab. Add each point to be generated by the TA Calibrator and the expected value for the UUT (unit under test) both As found (calibration done before adjustment) and As left (calibration done after adjustment) values. Points can also be generated with the help of AUTO button. By pressing this button, simply enter the maximum and minimum values of the calibration and the number of points that need to be generated considering the same steps and linear scale. Also fill the number of repetitions (REP) of the readings, and the calibration strategy (initial to the final point ↑, final to the initial point ↓, etc.). If 0 value is set in as found repetition, the task will execute only As-Left calibration.

Fig 26 - Task Points and Strategy

For SWITCH tasks, the screen is different, as shown in the figure below. It must be filled the TRIP POINT of the thermoswitch and its DEADBAND, as well as their respective error. The TIME RAMP is the time in seconds that the calibrator will take to tour the range and find the value of opening and closing the thermoswitch. The minimum value for this field is 300 s. Tip: If the Trip point and deadband are not known, try the THERMOSWITCH TEST to find an approximate value before creating the task.

3 - Safety Instructions

If the calibrator is turned on, do not leave the room without an identification or warning

about the high temperature hazard. Before turning the calibrator off, return the block temperature to values close to the

ambient temperature. Never remove the insert from the dry block or the thermo-elements from the insert,

while they are in temperatures far from the ambient. Wait until they reach the ambient temperature so that the heterogeneous cooling of the parts do not jam each other.

4 - Recommendations as regards Accuracy of Measurements

PRESYS Temperature Advanced Calibrators are instruments of high accuracy

level, requiring the observation of all the procedures described in this section, in order to achieve the necessary conditions to get the accuracy levels during the calibrations. Special attention should be paid in relation to the insert cleanliness. When necessary,

it should always be washed with water and soap, well rinsed and dried. Oil, grease, solid particles can hinder the heat transference to the insert and even jam the insert inside the block.

The sensor to be calibrated must fit snugly into the appropriate well. In case the sensor is loose, the measurement accuracy meaning can be completely senseless. The meaning of clearance between the sensor and the respective well should be understood in a subjective way and the common sense is very important. Thus, the sensor should enter the insert well (both completely clean) in such a way to stay snugly enough so that it cannot move or swing inside but it should not enter by force to get jammed.

In the specific case of generating negative temperature, the calibrations should be performed in a descending temperature order. This procedure is useful because in negative temperatures ice is formed in the insert surface and between the insert and the thermo-element being calibrated. This humidity changes the thermal contact and cause error in the calibration. After finishing the use of the insert below 0 C, increase the set point to a positive temperature value, remove the insert from the block and the sensor and dry completely all these parts before continuing the calibration. This procedure guarantees accuracy next to 0.1 C. In case you can accept higher values of accuracy, like 0.2 C or more, these cares can be left apart.

6.0 - Maintenance

6.1 - Instructions for Hardware Maintenance There are no parts or components inside the temperature calibrator that can be repaired by the user. Only the 10 Amp fuse for 115V models or 6 Amp fuse for 230 V models, placed within the socket on the rear can be replaced in case of blow.

The fuse may blow due to a voltage spike in the mains or a calibrator component fault. Replace the fuse once. If a second fuse blows again, it is because the fault is not that simple. In this case, contact the Presys technical support. In case of malfunction of mA input, the input fuse (250 V/32 mA) can be exchanged.

6.2 - Instructions for Insert Jamming

If it happens that an insert jams inside the block proceed as follows. 1 - apply a lubricant oil between the parts; 2 - apply cooling liquid inside the insert wells in order to contract the insert; 3 - try again to withdraw the insert. After taking the insert out, sand both the surfaces with thin sandpaper, polish

them with an suitable paste and finally clean the parts using alcohol or solvent.
